The Grace Instrument M7500 Ultra HPHT Dynamic Rheometer is a coaxial cylinder, rotational, high pressure, and high temperature rheometer. It is engineered to measure various rheological properties of fluids (including API HPHT tests) under a range of pressures and temperatures, up to 30,000 psi and 600 °F. An optional cement module is also available for testing the rheology of cements (see tab "Cement Rheometer", below.)
- The M7500 is built with a thick-walled steel pressure cell, which is surrounded by a fail-safe steel containment vessel to ensure operator safety.
- It is designed for easy test set up, sample loading and post-test cleaning.
- Cool-down after tests can be accomplished more quickly by connecting a tap water supply or a chiller into the M7500’s cooling fluid loop.
- Innovative patented design ensures against contamination of test sample with pressurization fluid.
- Recently patented design eliminates the need for fragile and expensive "V" jewel bearings.
- A computer-controlled, magnetically-coupled stirrer agitates the sample during testing
The M7500 is engineered for safe testing with extreme pressure and temperature settings:
- safe operation
- LCD display
- sample integrity
- PC interface
- repeatable results
- test flexibility
- low maintenance

More M7500 add-on modules:
M7500 add-on modules provide powerful new functionality at a lower cost than competing, stand-alone instruments, while maintaining a single instrument footprint and merging seamlessly with your existing software training. Click the tabs below to explore the various additional options available.
M7500PVT Ultra HPHT Pycnometer:
|The M7500PVT Ultra HPHT Pycnometer module measures dilametric changes in the density of a solid or fluid sample under conditions of temperature and pressure over a period of time. The patented M7500PVT Ultra HPHT Pycnometer replaces components of the M7500 Rotor/Bob assembly.|
More specifications and other information can be found on our M7500 Ultra HPHT Pycnometer page.
M7500LSM Linear Swell Meter:
The Grace Instrument M7500LSM Ultra HPHT Linear Swell Meter is an add-on module for the M7500 Ultra HPHT Dynamic Rheometer and provides an automated, ultra-high pressure and high temperature linear swell meter (up to 30,000 psi and 600 °F). Like the dedicated Grace Instrument M4600 HPHT Linear Swell Meter, it is engineered to measure the volumetric expansion (or contraction) of a solid sample under simulated downhole conditions while saturating it with a fluid sample.
More specifications and other information can be found on our M7500LSM Linear Swell Meter page.
M7500 HPHT Cement Rheometer:
The HPHT Cement Rheometer is an engineered insert for the M7500 Ultra HPHT Dynamic Rheometer that is designed for testing cement samples.
The cement sample is contained entirely within the rotor assembly, reducing contamination with pressurization fluid to a bare minimum. Once testing is finished, the rotor can be quickly disassembled for easy cleanup.
The patented design of the cement cell module eliminates jewel bearings, thus preventing measurement errors which can occur when bearings become contaminated with sample fluids. Visit the M7500 Cement Rheometer page.
M8500 HPHT Sag Tester:
The M8500 High Pressure, High Temperature Dynamic Sagging Tester is designed for evaluating barite and other weight material sag under simulated drilling conditions. (The M8500 option must be specified at time of purchase.)
More specifications and other information can be found on our M8500 HPHT Sagging Tester page.
